Using the Blended Learning Approach in a Quantitative Literacy Course

The efforts to improve the quantitative reasoning (quantitative literacy) skills of college students in the United States have been gaining momentum in recent years. At the same time, the blended learning approach to course delivery has gained in popularity, promising better learning with flexible modalities and pace. This paper presents the results of an exploratory study that compares student learning outcomes and student attitudes over several semesters of blended versus traditional delivery in the upper-division quantitative literacy course at Point Loma Nazarene University.     

How Community Colleges in Texas Prioritize Resources for Latino Men

This study explored how administrators at community colleges conceptualized change related to resource allocation and managing competing priorities to support targeted programming for Latino men. The study included the perspectives of 39 administrators from seven community colleges across Texas using concepts associated with institutional change to ground our analysis. Findings revealed that state and national initiatives, particularly those concerned with enhancing success for students of color, influenced how community college administrators approached change on their campuses. In addition, community college institutional mission, leadership, and a desire for data-informed resource management influenced the approach to resource allocation for Latino men.     

Adult stakeholder perceptions of 4th grade participation in children’s forest environmental education programming

An environmental education (EE) consortium located in the pacific northwest United States coalesced an external evaluation team to research its K-5 EE programming. The purpose of this article is to describe one phase of this program evaluation process including the exploration of adult stakeholder perceptions of EE programming accessed by 4th grade children. The author highlights the goals of the consortium and the context for the program evaluation, and the relevant literature addressing adult perspectives on EE is reviewed. The study framing, method, and qualitative results are reported. Findings suggest that adult stakeholders perceived positive impacts from 4th grade participation in EE, though the programming was viewed as being most beneficial to children coming from economically disadvantaged families. Implications for EE practice and research are discussed.     

A systematic review of self‐regulation strategies to improve academic outcomes of students with EBD

Self‐regulatory interventions have demonstrated numerous benefits for helping improve the academic performance of students. The purpose of this review was to report on the effectiveness and focus of academic self‐regulation interventions for children and adolescents with emotional and behavioural disorders. Thirty‐six studies published in 35 papers and involving 189 participants met inclusionary criteria. Overall, self‐regulation interventions showed moderate/medium effect size gains [percentage of nonoverlapping data (PND) 75%; standard mean difference (SMD) 2.27; Tau‐U 0.81] across academic subject areas. When assessing the effectiveness of self‐regulation interventions for addressing specific academic content areas, the largest ES gains were observed in reading (PND 93%; SMD 2.13; Tau‐U 0.94), although medium/moderate ES gains were observed in math (PND 71%; SMD 2.08; Tau‐U 0.70) and writing (PND 83%; SMD 2.57; Tau‐U 0.91). Self‐regulated strategy development, self‐monitoring interventions and strategy instruction were the predominant types of self‐regulation techniques implemented by researchers. There was evidence to support a claim of the generalisation and maintenance of findings. Implications, limitations and areas for future research are discussed.

基于改进蚁群算法的维吾尔文字图像分割

针对传统蚁群算法在维吾尔文字图像分割时容易产生缺陷和干扰的缺点,提出了一种改进的蚁群算法。该算法首先利用区域蚁群通过聚类中心对图像进行初步搜索和分割;然后再引入边界蚁群通过不同的路径选择信息素和策略更新手法来对图像进行边界补偿搜索;最后利用两种蚁群分别采用不同的路径选择信息素和筻略更新,共同实现对维吾尔文字图像精确分割的目标。实验结果表明,该算法准确分割出维吾尔文字区域,提高了其识别精度。     

The Talent Code: Greatness Isn't Born. It's Grown. Here's How

Abstract

We aimed to assess the extent of socioeconomic differences in sport and physical activity among Italian adults. A secondary data analysis of a multipurpose survey carried out by the National Institute of Statistics in 2006 in Italy was performed. We found marked differences in the practice of physical activity and sport by socioeconomic position. Subjects with a higher educational level were more likely to be physically active, practising more frequently both sport and physical activity. The Odds Ratio (OR) of regular physical activity for the highest educated compared to the lowest educated males was 1.70 (95% Confidence Interval [CI]: 1.38, 2.08), and the OR of sport participation was 2.03 (95% CI: 1.51, 2.72). Among females, the corresponding ORs were 1.32 (95% CI: 1.08, 1.63) and 2.26 (95% CI: 1.51, 3.38). Similar differences in physical activity and sport were found in relation to occupation and material conditions. Almost all sports were more frequently practised by subjects of higher socioeconomic status. Socioeconomic differences in sport and physical activity may derive from economic or cultural barriers. Policies to reduce inequalities and ensure access to sport independently of socioeconomic position are strongly needed.     

Referee bias contributes to home advantage in English Premiership football

Abstract

Officiating bias is thought to contribute to home advantage. Recent research has shown that sports with subjective officiating tend to experience greater home advantage and that referees' decisions can be influenced by crowd noise, but little work has been done to examine whether individual referees vary in their home bias or whether biased decisions contribute to overall home advantage. We develop an ordinal regression model to determine whether various measures of home advantage are affected by the official for the match and by crowd size while controlling for team ability. We examine 5244 English Premier League (EPL) match results involving 50 referees and find that home bias differs between referees. Individual referees give significantly different levels of home advantage, measured as goal differential between the home and away teams, although the significance of this result depends on one referee with a particularly high home advantage (an outlier). Referees vary significantly and robustly in their yellow card and penalty differentials even excluding the outlier. These results confirm that referees are responsible for some of the observed home advantage in the EPL and suggest that home advantage is dependent on the subjective decisions of referees that vary between individuals. We hypothesize that individual referees respond differently to factors such as crowd noise and suggest further research looking at referees' psychological and behavioural responses to biased crowds.
